P = I x V
Power = volts x amps
240 x 4 = 560 watts.
This is how much power will be consumed by the motor. The actual power produced at the shaft, will vary on type and efficiency of the motor.

In most of North America, the mains supply to the home is 120 volts. Thecurrent through a device dissipating 40 watts is 40/120 = 1/3 Ampere.In most of the rest of the world, the mains supply to the home is 220 volts.The current through a device dissipating 40 watts is 40/220 = 0.18 Ampere.
Wow, this could take all day depending on how deep you want to go! Current is the 'Juice' that flows through an electrical circuit. Current has been compared to water for explanation purposes. Voltage is the pressure that a system has, and current is the amount of water that flows through the system. A water tower is 100ft above the ground. Let's say that it has 100ft of pressure. This would be analogous to the potential difference (voltage). Water can flow through the pipes at 10 gallons per minute, in Electro-Speak; this would be the current (amps, amperage), particles of electricy per time unit, (particles/sec, particles/millisecond, etc.). In your house you have a lamp that operates a 120 Volts AC (alternating current, as opposed to DC - Direct Current like that in your car battery). The lamp is 120 watts (for ex.) therefore according to Ohm's law, the First Commandment of Electricity), the lamp draws 1 amp. Current (I) = Power (watts)/Voltage, Therefore 10 120w lamps = 1200 watts (like a hair dryer) draws 10 amps, a 60-watt lamp bulb would draw half an amp (0.5a). Current is also X# Coulombs per second, a coulomb is (whole bunch) of Joules/second. A Joule is a tiny particle of energy.
Gravity
The force that draws the two galaxies together is gravity, the same force which keeps the Earth rotating around the Sun and us on the Earth!
1.7amp
Yes. It draws less current.
The formula you are looking for is W = I x E.
11.5 x 240 = 2760W motor.
P=VI so I=P/V I= 60/230 I=0.261 A
An electric motor draws current from the battery. The amount of current is determined by the position of the accelerator. Most vehicles use a pulsed DC current that is turned on and off depending upon the speed of the vehicle. A hybrid uses an engine that usually runs at a constant speed, charging the batteries as you go. The speed of the engine in the hybrid is usually set for about 35 mph. At this speed, you are drawing the same amount of current that the engine is supplying. At faster speeds, the electric motor draws more on the battery than the engine can supply for a limited distance at higher speeds.
Power = Volts * current [p = E*I]; 120volts*10amps = 1200watts

Likely one of the two electric elements is going out which creates very high resistance in the circuit and therefore draws very high current (amps) and causes the breaker to trip.
4800 watts because watts = volts x amps.
Here are a couple. Assuming everything is "normal" here, if you drop a bagel in the toaster and turn it on by pushing the lever down, the AC current the toaster uses (draws) will stabilize after a few seconds and stay constant. If you turn on your car's headlights, each lamp will draw a constant current from the DC source after a few seconds of "warm up" time. Those are examples of constant electric current.
It will increase the current since the water heater is made of a heating element and which is resistive in nature. Ohms law states that V=IR where V is the voltage, I the current and R the resistance. Now the resistance will always remain constant. Thus, when the voltage is increased, the current will also increase.
